Daniel, I see the exact same message issued for my "/usr" RO filesystem. In my case, the minidisk in zVM is RR for the owner and linked RR by all sharing Linux guests. On my system, it seems to be caused by DB2/UDB accessing programs living in "/usr", but I have been unable to determine why. I've posted the question to the list in the past and followed all of the recommended suggestions.
Hank Calzaretta, Moore Wallace -----Original Message----- From: Daniel Jarboe [mailto:[EMAIL PROTECTED] Sent: Friday, May 30, 2003 10:29 AM To: [EMAIL PROTECTED] Subject: End_request: I/O error Any ideas what could cause this in console log (and /var/log/messages).

It seems to happen with squid activity. I have to wonder if it's more than something trying to write to the R/O portions of the filesystem because if I do a touch then I get an error in my shell "touch: creating `blah': Read-only file system" but none of these I/O error messages. This is with basevol+guestvol disgussed in Large Scale Linux sg246824. It's interesting that they are different sectors, but fairly close together. RH 2.4.9-43 under z/VM. That device is also defined vm-wise to another image (R/W), but that other image is not up.
